1 Claim. (Cl. 155-123) This invention generally relates to knapsackcarriers.

The object of the invention is to provide a knapsack carrier which isconvertible into a camp stool.

The knapsack carrier according to the invention is composed of twopreferably bracket shaped parts which are pivotally interconnected so asto be foldable from a collapsed position in which the planes of thecarrier parts substantially coincide, into an extended position in whichthe planes of the carrier parts intersect, the carrier parts havingattached thereto a seat member forming with said carrier parts a camp orfolding seat.

According to a preferred embodiment of the invention, one of the carrierportions has hinged thereto adjacent the seat member one end of apreferably rectangular plate which is foldable from a position ofnon-use in which it extends along the plane of the carrier parts intheir collapsed position, into a position of use at rightangles thereto,said plate having hinged to it adjacent its opposite end a supportingmember adapted to support said plate in its position of being soextended in which the plate forms a table top adjacent the camp stoolwhen the latter is in its extended position.

The table top may comprise a plate of sheet-metal or the like adapted tobe carried by the legs of a U- shaped bracket the extreme ends of thelegs of which are hinged to one of the two carrier parts.

According to a further development of the invention, the ground-supportcomprises a substantially U-shaped bracket the extreme ends of the legsof which are hinged to the intervening portion of the bracket carryingsaid plate whereby the supporting bracket is foldable into a collapsedposition close to the plate forming the table top.

Where one of the knapsack carrier parts is provided with a conventionalhip supporting yoke it is possible, according to a preferable embodimentof the invention, to provide the intervening portion of theplate-carrying bracket with a projection or bulge which is adapted inthe collapsed position of the carrier parts and when the plate-carryingbracket is folded down against said parts, to be snapped into engagementwith said hip supporting yoke whereby the plate-carrying bracket isreleasably retained in its position of being thus folded down.

One specific embodiment of the invention will now be described by way ofexample in conjunction with the accompanying drawings, in which:

Figure 1 is a side elevational view of a knapsack carrier converted intoa camp stool and table and constructed in accordance with the invention,the stool and table being shown in its position of use.

Figure 2 is a top plan view corresponding to Figure 1.

Figure 3- is a rear view of the carrier with the stool and table intheir collapsed position.

Referring to the drawings more specifically, the knapsack carrierillustrated therein consists of two parts 1 and 2 bent from metallictubular material and one of which, 2, has the shape of a closed bracketor frame member while the other, 1, is bent to the form of a PatentedJan. 26, 1960 U-shaped bracket of a width slightly less than theinternal with of the bracket or frame 2, said two brackets beingfoldably interconnected, by aligned pivots 30 so as to enable thebrackets to be folded from a collapsed position in a common plane(Figure 3) into an extended position shown in Figures 1 and 2 in whichthe planes of the two brackets intersect at the pivot axis. Attached tothe upper intervening portions 3 and 4, respectively, of the twobrackets is a rectangular sheet of leather or fabric which is adapted inthe last-mentioned position of the brackets 1 and 2 to form a seat whenthe knapsack carrier is placed on the ground. The knapsack 6 is attachedat its upper end by means of straps 7 or the like to the upper portion 3of the bracket 1, and is attached at its bottom end by means of straps 8or the like to the lateral portions or legs of the bracket 2 near thelower ends of these lateral portions or legs. Extending from thefirstmentioned straps 7 are two shoulder straps 9 which are passed abovethe seat 5 and, in the vicinity of the top portion 4 of the bracket 2,through openings in said seat, the ends of said shoulder straps areattached to fastening loops 10 arranged at the ends 11 of a hipsupporting yoke 13 interconnecting the extreme or lower ends 12 of thelegs of the bracket 1. Attached to further fastening loops 14 arrangedat the ends 11 of the hip supporting yoke 13 are the ends of a hipsupporting belt 14a. In the collapsed position of the brackets or frames1, 2 the latter form a carrier for the knapsack 6, whereas in theirextended position they will form together with the seat member 5 a campor folding stool when the knapsack is placed upended on the groundsurface.

Combined with the knapsack carrier is a table comprising a rectangularplate 15 being bent over at two opposite marginal portions 16 to engagearound the legs 17 of a U-shaped bracket, the'extreme end portions 13 ofsaid legs being bent around the top base portion 4 of the bracket orframe 2 whereby the bracket 17 carrying said plate 15 is foldable fromits position of non-use close to the collapsed brackets 1, 2, as shownin Figure 3, into its position of use illustrated in Figures 1 and 2.Hinged to the base portion 19 of the U-shaped bracket 17 carrying theplate 15 is a U-shaped supporting bracket 20 the extreme end portions 21of the legs of which bracket are bent around the bracket portion 19, thesupporting bracket or ground-support 20 being thus foldable from itsvertical supporting position shown in Figure 1 and inwardly into aposition close to the plate 15. The base portion 19 of the bracket 17carrying the plate or table top 15 is formed with a bulge orprotuberance 22 which is adapted, as the bracket 17 is folded againstthe collapsed carrier brackets 1, 2 after the supporting bracket 20 hasbeen folded upwardly against the plate 15, to snap over the upper edgeof the hip supporting yoke 13 whereby the brackets 17 and 20 will bereleasably retained in their position of being folded down against thecollapsed carrier brackets 1, 2.

From its collapsed position illustrated in Figure 3, the knapsackcarrier can be converted by a few simple manual motions into theposition illustrated in Figures 1 and 2 offering not only a seat butalso a table for provisions brought on the excursion.

It is understood, that the invention is not restricted to the embodimentdescribed hereinbefore and as illustrated in the accompanying drawingwhich is susceptible of various modifications as regards its componentparts without departing from the scope of the invention.

What we claim is:

A knapsack carrier comprising a pair of members each having a pair ofside portions and at least one end portion connecting said sideportions, said members being pivotally interconnected at their sideportions for being pivoted from a collapsed position in which the planesof said members substantially coincide, into an extended position inwhich the planes of said members intersect, a flexible seat connected tosaid end portions of said members limiting the pivoting of said membersto an extended seat forming position, a knapsack connected to an endportion of one of said members adjacent said seat and connected to theother of said members at the extremities of the side portions thereofremoved from its seat connected end portion, said seat having openingstherethrongh adjacent its connection to the other of said members, aplurality of shoulder straps connected to opposite ends of said one ofsaid members and extending through said seat openings for drawing saidmembers to their collapsed positionwhen said carrier is picked up bysaid straps.
